The 3 Fatty Foods a Doctor Swears by For a Metabolism Boost

If someone's trying to be more health conscious, they often avoid ordering meals or choosing groceries associated with the ever-elusive substance called fat. But as holistic women's health and anti-aging doctor Jamé Heskett, MD, jokes in Mindbodygreen, "Butter is the bad guy — or is it? Olive oil’s a hero, but coconut oil’s better?" It's hard to keep up, but Heskett sets the record straight. In fact, essential fatty acids are "crucial for your cells to function optimally," she says. Read on for the types of high-fat foods that are medically proven to boost your metabolism, ensure heart health, ease digestion, and enhance focus:

Eggs or Poultry

We need protein to fuel us throughout the day; without it, we wouldn't have the energy we need to stay focused. Plus, protein is essential to regular metabolic function, according to this study from The American Journal of Clinical Nutrition. But eggs and poultry are not only a source of protein but they're also omega-6s, making them a great way to get your essential fatty acid eating on.

Avocados

In case you need yet another excuse to order that avocado toast, this research trial published in The Nutrition Journal found that avocado consumers had significantly healthier metabolic rates. Packed with vitamin E, avocado is a great healthy fat to eat for better immunity. Wellness physician Josh Axe, DNM, DC, CNS, says they're also great for anti-aging since vitamin E helps prevent wrinkles.

Salmon

If you're not about taking fish oil supplements, you're in luck: Just eat more salmon and reap the same benefits. Chock-full of fatty acids and omega-3s, salmon lowers blood pressure, decreases inflammation, and keeps your metabolism in check, as confirmed in this article from The University of Maryland Medical Center. With a million delicious ways to prepare it, there's a reason it's a staple in heart-healthy and non-restrictive diets alike.
